The Light that flows through your system is Universal Energy. It is the Light of the Universe. You give Light form. What you feel, what you think, how you behave, what you value and how you live your life reflect the way you are shaping the Light that is flowing through you. They are thought forms, the feeling forms and the outer forms that you have given to Light. They reflect the configuration of your personality, your space-time being.
And how does one go chasing after a glimpse of the uncreated Light? The Hesychasts, high on Mount Athos, bowed their heads upon their breasts, took a deep breath, and plunged in. What they plunged into was prayer. It began with a tack with which to fix the attention. It became breath itself, an inlet for the universe to invade one's body until the entire cosmos, drawn in, heaved out, was transformed into prayer. The body's posture was important. The breathing was to be carefully controlled so as to keep time with the words. Eventually the prayer, breathed in, united with their very blood and heartbeat; breathed out, it blessed the world. And some monks claimed after a while to have indeed seen the Light of the Transfiguration, uncreated energy beheld by bodily eyes.
